,SPRING-ATTACHING our.

Application filed January 16, 1914., Serial No. 812,566. 1

T0 at whom it may concern Be it known that I, PHILIP J. KNAUFF, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a new and useful Spring-Attaching Clip, of which the following is a specification.

My invention relates to certain improvements in attaching clips for springs andhas for an object to provide a clipof simple construction which is adapted to easily and at the same time rigidly engage one convolution of the spring and to encircle the ratan or cane for the securing of the spring thereto.

A further object is to provide a spring attaching clip which is struck from a blankchanges in the precise embodiment of the in.

vention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the drawings accompanying this specification and forming a part thereof,, the preferable form of my invention is illustrated, in which Figure l'is a view in perspective of a ratan and spring coil with my improved spring attaching clip secured thereto. Fig. 2 is a blank forming my improved spring attaching clip prior to the bending of the same for engaging the spring and cane. Fig. 3 is a cross sectional view taken on the line 33 of Fig. 1.

Referring to the drawings in which similar reference numerals designate corresponding parts throughout theseveral views, 4 is a ratan or cane and typifies the ordinary strip over which the canvas is drawn in a box spring of the ordinary construction. A helical and spiral spring coil 5 is illustrated in Figs. 1 and 3 and is secured to the ratan or cane 1 by my improved spring attaching clip.

My improved spring attaching clip comprises in blank a body portion 6 which is provided with the slots 7 adjacent the ends Specification of Letters Patent. i

thereof and through which a convolution of v the spring 5 is adapted to pass when the blank is bent into the form illustrated inFigr 1; Extending at right angles to the longitudinal axis of the body portion 6 are the arms 8 between the outer extremities of which extends the cross member or rod 9. j

Located upon-opposite sideslof the bodyportion 6, are the fingers- 10 which are spaced apart a distance less, than the spacing of the arms 8 and are so positioned with respectto the latter thatthey will when benttoward the same extend therebetween so as to, be ca- 5 pable of engaging the rod or crossmember 9.

The blank is preferably formed fromia sheet of thin metal so that the body portion will be capable of ,bending along the longitudinal line 11. Theclip is first Ibent upon the line 11 of the body portion .so as to define the ledge 12 and the flange 13. The end of one, convolution ofthe spring 5 iswthen passed through one ,of the openings 7 and out of the opposite opening t and due to the i fact 1 that the line 11 along which the body portion is bentis substantially tangential to one'side of the opening 7 the wire of which the spring is formed will contact with the under surface of the ledge 12 as illustrated in Fig, 1.

,The ledge 12 is made ofa width HPPI'OXl-li -mately equal to the diameter of the ratan or cane 4 so that the fingers 10 will extend at right angles to the ledge 12 and engage the cross member or bar 9 which is brought in such relation by reason of the arms 8 being circled around the cane 4. In order to facilitate the bending of the arms 8 and to further provide that the said arms and flange 13 will tightly and forcibly engage the cane 4, suitable openings 14 are provided in the extremities of the arms 8 and into which the end of a pair of pincers may be inserted or other device which will contact and engage the ledge 12 and the slot 11 so as to draw the same together, after which the fingers 10 her 9 allows the fingers 10 to engage the even though the ratan be of decidedly Lin-- even contour, the fingers Will engage" some portlon of the bar 9.

The/improved clip maybe used to secure a spring coil as illustrated Fig. 1, although it is to be noted that in the ordinary use of the" (lfiib the i 'atait' Will be secured to the top ef can sueh whale be ohtaiffed weftll' struetttetn Fig. iiivfted; Having hus f" ny ees'enhea my hive-neon, whet I elaiin is a 1'.
